This compact module is designed for OEM application such as drone thickness measurement or ILI (inline inspection) tools. EMAT (electromagnetic acoustic transducer) technique enables non-contact thickness measurement on ferromagnetic tube/plate/bar products. Thickness measurement can also be performed on other conductive materials such as stainless steel, titanium, aluminum, brass, thanks to our unique algorithm and transducer design. Additional advantages of using EMAT is no need of couplant, high tolerance to rough surface, reading through scale, paint or coating up to 4 mm.
